Change. We talk a lot about it but how often does it truly happen in the way we want it to? There are all sorts of studies, speeches and books dedicated to the concept and yet, it sometimes seems nebulous.

One of the really interesting questions that I often hear - and ask myself - is whether people can ever truly change.

Can someone who has committed a grievous crime be truly rehabilitated? Can someone who has traditionally been socially conservative become extremely liberal, and/or vice versa? Can someone who hates sport turn into an ironwoman/man?
